A new optical frequency comb uses two lasers and a tiny chip to simplify precision measurements, opening a path toward smaller atomic clocks.

The name "nuclear clock" might conjure up images of nuclear power or massive machinery. However, two studies published ...

Two teams of scientists have built the first working "nuclear clocks", which could become the world's most accurate timekeepers. The clocks could be used in navigation, mining, earthquake prediction, ...

For a clock that keeps time with laser light, even a slight shift in the laser’s frequency changes its rhythm. Researchers in ...

The heart of a minuscule atomic clock—believed to be 100 times smaller than any other atomic clock—has been demonstrated by scientists at the Commerce Department’s National Institute of Standards and ...

Physicists like to measure things, and they like those measurements to be as precise as possible. That means working at unfathomably small scales, where distances are much smaller than even the ...

Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards and Technology (NIST) campus in Boulder, Colorado. NIST-F4 measures an ...
